Pipette tip automatic cleaning device

Abstract

The invention provides an automatic cleaning device of a liquid shifting gun head. The automatic cleaning device of the liquid shifting gun head comprises a cleaning liquid tank for accommodating cleaning liquid, a pump, a hollow pipe, a spraying head, a liquid shifting gun head bracket for inserting in the liquid shifting gun head, a spraying hole, a waste liquid tank, a dirt discharge port, a cleaning tank, and an automatic control system for controlling the automatic cleaning device of the liquid shifting gun head to actuate preset cleaning procedures; the spraying head is arranged at the top in the cleaning tank; the liquid shifting gun head bracket is arranged rightly below the spraying head in the cleaning tank to enable the liquid shifting gun head to correspond to the spraying head one to one; the spraying hole is formed in the side wall of the cleaning tank, and is corresponding to the tip end of the liquid shifting gun head inserted in the liquid shifting gun head bracket; the waste liquid tank and the dirt discharge port are formed in the bottom of the cleaning tank; and the cleaning liquid tank is connected with the cleaning tank through the pump and the hollow pipe for pumping the cleaning liquid to the spraying head and the spraying hole. The automatic cleaning device of the liquid shifting gun head can effectively solve the cleaning problem of the liquid shifting gun head, and realizes five-in-one cleaning process of systematicness, environmental protection, safety, thoroughness and fastness.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to an automatic cleaning device for pipette tips. Background technique [0002] A pipette is a kind of pipette, which is commonly used in environmental monitoring, pharmacy, medicine, TFT-LCD (thin film transistor-liquid crystal display) and other industrial laboratories to pipette a small amount or trace amount of liquid. For example, liquid crystal contamination analysis in TFT-LCD industry, liquid crystal melting point and clearing point test, photoresist concentration analysis in stripper, etc. [0003] Pipette guns of different specifications use different sizes of pipette tips, and the shapes of multi-channel adjustable pipette guns produced by different manufacturers are also slightly different, but the working principle and operation method are basically the same. When in use, first press the button to the second stop point, then slowly release the button to the origin...

Problems solved by technology

[0004] The pipette is equipped with tips of different sizes. The material of the pipette tips is a reusable material. However, due to the small diameter of the pipette tips, the frequency of use is large and fast. Currently, for this There is no relatively mature cleaning method for pipette tips. Therefore, in order to avoid cross-contamination between samples, many laboratories use disposable use, which increases the cost of equipment consumables to a certain extent, and also forms a certain waste of resources.

If the traditional "manual + fine brush" cleaning mode is used, not only the workload is huge, but also it is not easy to clean, which will affect the secondary use effect
